Thank you to all of the volunteers, the 4-H Agricultural Society and Board members, extension staff and all the youth and families who helped make the York and Seward County Fairs a success in 2021! It was a joy for me to see ‘normal’ fairs, young people and adults excited to check out their projects and show off their ribbons, the number of people attending the activities, walking around the buildings and just talking between. them !

Thank you also to the crop advisers and agronomists in the agricultural industry who submitted samples during the fair and kept me informed of what you see in the fields! Southern rust was also confirmed in Hamilton and York counties this week. Frog eye leaf spot also appears on some soybeans due to the high humidity and dew on the soybean leaves.

Many have asked why crops don’t use a lot of water. ET is evaporation from the soil and leaf surface + transpiration (the process of water loss through the stomata of the leaves) of the crop. The high humidity kept the plants moist, especially the soybeans, longer during the day (which is why I think the use of soil moisture showed up less on the soybeans than on the corn) . I know many, myself included, have learned that crops automatically remove 0.30 “+ per day during panicle and bloom, but that just isn’t true. That way of thinking doesn’t hold up. not account for the environmental factors at play which change every day of every year. Higher ET occurs on sunny days with high heat, higher wind and low humidity. Cloud cover, humidity and low wind reduce all ETs (and we’ve had a lot of them lately.) As I’ve worked with farmers over the years, I’ve heard a lot about how useful their ET gauge is, as it’s a visual representation about what is happening with the environment and crop water use. If you do not have an ET gauge, the UBBNRD shares the daily use of the high crop water by email. Plains Regional Climate Center, so you can contact Marie there if you want to aite this information. each day. Fortunately, the humidity allowed the rain-fed crops to hang on for longer, due to the decrease in the crop’s water demand, despite the harder humidity for us and the animals.
